Problems solved by technology

Especially in the case of small-area patterns and texts, if some patterns or texts are only 1-2mm or even smaller, so that the bright marks after transfer are larger than the pictures and texts, which seriously affect the appearance quality of the transferred products

Embodiment 1

[0018] In Example 1, as shown in FIG. 1, the bottom layer of the transfer film is a PET carrier film 1, the second layer is a release layer 2, and the third layer is a graphic layer 3.

[0019] The formula of the release layer 2 (by weight ratio) is :

[0020] Water-soluble mineral wax: 2-6%

[0021] The ratio of water and alcohol is 1:1: 94-98%

[0022] Mineral waxes are Montan wax, montan wax and the like. If it is oil-soluble mineral wax, dissolve 20 grams of mineral wax in 5 kg of a mixed solution of toluene and methyl ethyl ketone. Toluene and methyl ethyl ketone each account for 50% of the mixed solution.

[0023] The formula (by weight ratio) of one color ink in the graphic layer 3 is:

[0024] Polyacrylate copolymer resin produced by Degussa, Germany: 17%

[0025] Pigment: 7%

[0026] Phosphate lipid anionic surfactant: 0.5%

[0027] Polyethylene wax produced by American Sanye SHAMROCK Company: 1%

[0028] Toluene: 49.5%

[0029] Butyl acetate: 25%

[0030] The above co...

Embodiment 2

[0031] In Example 2, the formula (in terms of weight ratio) of the release layer 2 can also be:

[0032] Solvent-based silicone produced by Rhodia, Germany: 100 parts

[0033] Catalyst produced by Rhodia, Germany: 1.2 parts

[0034] Mix organosilicon and catalyst and dilute to 6-8 times with 120# gasoline.

Embodiment 3

[0035] In Embodiment 3, in the formula of the release layer 2, synthetic wax (such as polyethylene wax, polypropylene wax, etc.) can also be used instead of mineral wax, or mineral wax and synthetic wax can be mixed together for use.

[0036] The production process is: (1) First, corona treatment of the carrier film to make the surface tension of 500μN / cm or more, so that many tiny pores will be formed on the surface of the carrier film, so that the surface of the carrier film has good printability; (2) Coat the corona surface of the carrier film with a coater or print a release layer with a printer. The release layer can be tightly combined with the carrier film, and it is easily combined with the carrier film under the action of heat or pressure. The image and text layer is detached, and will not be transferred to the surface of the product with the image and text layer; (3) The required image and text layer is printed on the release layer. This image and text layer combines dec...

Abstract

The invention discloses an impression-transfer film and producing craft, which is characterized by the following: the impression-transfer film installs tripping inlay, graphic inlay; the tripping inlay and carrier film bind compactly; the graphic inlay has decorative, lastingness, weatherability, heat sensitivity and adhesiveness; the carrier film carries out corona dispose to make the interfacial force higher at 500 muN / cm; one layer of abjunction layer is coated or printed on the corona surface of carrier film. The invention keeps the product bright, which makes the appearance surface more beautiful.

Description

Technical field [0001] The invention relates to a plastic hot press transfer film and its production process. Background technique [0002] The existing hot press transfer film is composed of a carrier film, a release layer, a protective layer, an image and text layer, and a heat-sensitive adhesive layer. Go out of the layer. Under the action of heat or pressure, all the coatings on the heat press transfer film except the carrier film can be firmly adhered to the surface of the plastic product, which is a printing film with certain functions. Chinese patent CN1175979C discloses a production process of transfer film: according to the size of the image and text range or the size of the transferred surface of the transfer body, a transparent or semi-transparent protective layer is printed at a certain interval by a printer. A layer of required graphics and text is printed on the protective layer, and a thermally sensitive adhesive layer corresponding to the size of the protective la...
